## Questions & Answers

**Q: Is the subwoofer frequency knob an adjustable low-pass filter?**
A: Yes frequency and gain aka volume separate from volume for everything..aswel as a slider volume so you can set the max anyone can turn the volume up..so they don't blow ..

**Q: If I was hook this up in my vehicle with about 13.6vdc-14.1vdc and 50-60amps then will it work or blow? If it’ll work then how many watts/channel???**
A: I had the slightly weaker version setup in my vehicle. I wired the front speakers to the two speaker channels, and ended up wiring my rear 6x9s in series and wired those to the subwoofer channel. You must be careful with impedances if you do this to make sure you don't blow your speakers. But doing this gave me very good sound for not having an actual subwoofer. A dedicated, high power amplifier will have way more bump for an actual subwoofer, however, if you're ok with the idea of using your rear fill as a stand-in subwoofer, wire it up how I described and it'll sound pretty good. I also used a DC-DC buck converter to step my vehicle's 12-14V DC up to the optimal power level for the amplifier. They're all over amazon just search the input power by the output power and the amp rating and you'll be good to go.

**Q: Fuente recomendable para este equipo?**
A: ¿Quieres decir qué tipo de energía necesita?
La fuente de alimentación de 12V-36V / (5-15A) DC puede impulsarlo. Si desea obtener una entrada de alta potencia, primero debe aumentar el voltaje de entrada o reducir la impedancia del altavoz.

**Q: To run a 4ohm sub and 4 ohm speakers what ah should I get for the 36v power supply?**
A: This need depends on your needs, if your speaker power is relatively large, then it is recommended to use 36V. If the power of the speaker is not very large, the 24V DC power supply can also drive your speaker.
